The development of mechanical fuel control system to electronic fuel injection in diesel engines has presented the opportunity to implement additional engine con-trol mechanism to improve engine performance and controls. In this thesis, an electronic governor system was designed for use on a 2TNE68 micro diesel en-gine generator in the Technobothnia laboratory.
The electronic governor system was designed in Technobothnia laboratory. This system was designed with specification to replace an existing mechanical gover-nor system of the engine and the technique used was a link mechanism of a step-per motor and drive.
However, double flexible coupling and torque sensor were selected for easy and efficient alignment as the engine is coupled to the generator. Other sensors were selected to monitor, control and ensure the smooth running of the generator set. A simple installation and maintenance manual was designed and the whole unit (generator set) was designed using NX Software.
The generator set was successfully designed but was not assembled because our main task was only to design the generator set for the laboratory’s technician to assembly. The complete designed work was handed over to our supervisor which will be later given to the laboratory technician for assembling.
